阅读理解。 Have you ever had problems in your life and don't know how to be happy? If so, you will find Being a Happy Teenager written by an Australian writer Andrew Matthews useful. In his book, Matthews tells us how to have a happy life and answers the questions of teenagers. There are many subjects, such as parents and friends, and the book says we should stop being angry and learn to forgive. ① The book tells us some useful skills, such as how to put what you have learned into pictures of your mind to make your memory better. Many teenagers think that ②______ comes from a good exam result ③______ praise (表扬) from other people. But you can still be happy when there are no such 'good' things. Success comes from a good attitude, you learn from thinking about things in a positive way. If you are tall, people notice you and you can get a better view at the movie; if you are short, your clothes and shoes take less room in your bedroom! This is Matthews' most important lesson: you choose to be happy! 1. 将画线部分①处译成汉语。 _____________________________________________________________________ 2.
